Here, an adhesive material is applied on the display protection unit 1120, and the information display unit may be attached to the display protection unit 1120 via the adhesive material.

The communication unit 120 transmits the motion information of a ball to an external terminal 120 through a wireless communication method, and a user may check the motion information transmitted to the external terminal 120.

Referring to FIG. 4 to specifically describe the communication unit 120, the communication unit 120 is configured to include an output control unit 1210, a wireless communication unit 1220, and a location communication unit 1230.

The output control unit 1210 may function as a control unit for controlling operations of each of the units including the display unit 110, the communication unit 120, the power supply unit 130, the sensor unit 140, and the like.

Also, the output control unit 1220 may control an ON/OFF operation of the power supply unit 130 according to operation control information by receiving the operation control information from the external terminal 120.

When the operation control information includes a command for turning OFF an information display function or a sensor activation function of the ball 10, the output control unit 1220 outputs a control signal for deactivating the relevant function, whereby the power supply to the relevant unit may be deactivated by the power supply unit 130.

The wireless communication unit 1220 may transmit the motion information of the ball to the external terminal 20 using a wireless communication method, such as Bluetooth, Wi-Fi, Wibro, and the like.

The wireless communication unit 1220 may include an antenna and a communication module for wireless communication.

The location communication unit 1230 may collect in real time GPS information of the point at which the ball 10 is located.

The power supply unit 130 may supply power to each unit that operates by being supplied with the power, such as the display unit 110, the communication unit 120, and the sensor unit 140.

Referring to FIG. 5 to specifically describe the power supply unit 130, the power supply unit 130 is configured to include a solar cell 1310, a charging unit 1320, and a storage battery 1330.

The solar cell 1310 is exposed to the outer surface of the ball to collect solar energy, and may convert the collected solar energy to electric energy.

The acceleration sensor unit 1410 may measure acceleration information generated as the ball 10 moves.

The location information sensor unit 1420 may measure movement distance information of the ball 10 by collecting GPS information.

In this case, the location communication unit 1230 may deliver the collected GPS information to the location information sensor unit 1420.

In this case, using the acceleration information and the movement distance information, the acceleration sensor unit 1410 may calculate speed information such as the average speed, the maximum speed, and the like.

The energy measurement unit 1430 measures time information for which the ball 10 moves, and may calculate the calorie information that a user consumes hitting or kicking the ball using the time information and previously input physical information.

The impact sensor unit 1440 may calculate the impulse information applied to the ball 10 using the acceleration information.

The lighting unit 160 may output a different color of light depending on at least one piece of information among the acceleration information, the speed information, and the impulse information, which are collected and calculated by the sensor unit 140.

For example, white light, yellow light, and red light may be output when the speed of the ball is less than 90 km/h, greater than 90 km/h and less than 120 km/h, and greater than 120 km/h, respectively.

Also, for another example, depending on the magnitude of the acceleration or the magnitude of the impulse, the color of the light may be differently output as white, yellow, or red.

In this case, the lighting unit 160 for outputting various colors is covered with the covering 15 of the ball 10, and the part of the covering 15 for covering the lighting unit 160 may be made of a transparent material.

On the other hand, the display unit 110, the communication unit 120, the power supply unit, the sensor unit 140, and the lighting unit 160 may be distributed inside the ball or may be fixed using wire supports from the center of the ball so that the center of gravity of the ball 10 is at the center of the ball 10.

In this case, to adjust the center of gravity of the ball 10, the center-of-gravity control unit 150 may be additionally disposed inside the ball.

FIGS. 7 and 8 are views illustrating an internal structure of a ball with an information display function according to an embodiment of the present invention.

Referring to FIG. 7, the display unit 110 and the solar cell 1310 may be attached on the inner surface of the covering 15 of the ball 10.

In this case, the display unit 110 and the solar cell 1310 are covered with the covering 15 of the ball 10, but the parts of the covering 15 for covering the display unit 110 and the solar cell 1310 may be made of a transparent material.

In this case, the display unit 110 and the solar cell 1310 are connected with a central circuit unit 1000 through an electric wire 11 so as to give and receive a signal or power.

The central circuit unit 1000 including the communication unit 120, the power supply unit 130, and the sensor unit 140 is located at the center of the ball 10, and the central circuit unit 1000 may be fixed to the covering 15 of the ball by being connected to the wire support 12.

In this case, the wire support 12 may be made of materials such as elastic steel, rubber, or plastic.

On the other hand, it is possible to locate the center of gravity of the ball at the center of the ball by dispersively disposing the center-of-gravity control units 150 of which the weight corresponds to the weight of the display unit 110 and solar cell 1310, on the inner surface of the covering 15 of the ball 10.

In this case, the center-of-gravity control units 150 may be arranged both on the point opposite the display unit 110 and on the point opposite the solar cell 1310 so as to form a cross shape.

Also, assuming a virtual line perpendicular to the cross-form of a extension line, which is generated by arranging the center-of-gravity control units 150 respectively opposite the display unit 110 and opposite the solar cell 1310, it is desirable to additionally arrange the center-of-gravity control units 150 on the both points at which the virtual line meets the covering 15 of the ball 10.

In this case, it is desirable that the weight of the display unit 110 is the same as the weight of the solar cell 1310.

In this case, as shown in FIG. 8, depending on the locations of the display unit 110 and solar cell 1310, a plurality of center-of-gravity control units 150 of which the weight corresponds to the weight of the display unit 110 and solar cell 1310 may be dispersively disposed on the inner surface of the covering 15 of the ball 15.

In this case, the number of the center-of-gravity control units 150 is not necessarily four. Depending on whether the solar cell 1310 exists and depending on the dispositions of the display unit 110 and the solar cell 1310, both the number and the location of the center-of-gravity control units 150 may be changed.

Also, when each of the units included in the central circuit unit 1000 is dispersively disposed on the inner surface of the covering 15 of the ball 10 rather than disposed at the center of the ball 10, it is possible to dispersively dispose the center-of-gravity control units 150 at random locations on the inner surface of the covering 15 of the ball to adjust the center of gravity.

Also, removing the solar cell 1310, the center-of-gravity control unit 150 may be disposed at the location of the solar cell 1310 to substitute the solar cell 1310.

Also, when the lighting unit 160 is disposed on the inner surface of the covering 15 of the ball 10, the center-of-gravity control unit 150 of which the weight corresponds to the weight of the lighting unit 160 may be additionally disposed inside the ball.
